Executor Logger

When you execute a request, the execute method will throw an
exception if a robot generates an error. Other types of errors and
warnings are reported through an executor logger, a
class implementing the IExecutorLogger interface.
In the previous examples, we have not provided any
execution logger when executing robots, which means that the default
implementation ExecutorLogger that will write to system out
will be used. Let's see how the ExecutorLogger will report
if one of our RoboServers goes offline.

The example configures a cluster with a RoboServer which is not online.

Often you don't want to have your application writing directly to
System.out, in that case you can provide a different
IExecutorLogger implementation, you can do so when
registering the cluster, like this

Request.RegisterCluster(cluster, new DebugExecutorLogger());

Use
DebugExecutorLogger

This example uses the
DebugExecutorLogger() which will also print to
System.out, but only if the API debugging is enabled.
Alternative you can provide your own implementation of the
ExecutorLogger, to control how error messages should be
handled.
